Looking for some tall aero rims(7 posts)

Looking for some tall aero rimsJ.S.
Jun 18, 2001 3:26 PM
to build with a set of Hugi hubs. I'd like something taller than a CXP33, maybe in the 40-50mm range. Does anybody have info on a manufacturer of rims like this. Thanks

I darned near had a coronary when I looked up the price($300.00 per rim). Thanks for the info though.

Except that 3mm shorter than the CXP-33.

To be honest, you don't get proper deep rims with-out paying stupid money. I don't know why, maybe the materials / techniques needed to make the rim strong enough?

Or just marketing. Who's to say...

While it is possible to make 50mm deep cross-section aluminum rims, they would be very heavy. Aluminum rims are made by forcing a block of alloy though a dye at extreme pressure. The dye can be designed to make any shape of rim, box, round, or in this case tall. Tall cross-section Al rims would be heavy because aerodynamic ‘nose-cone' portion of the rim would have to be made of the same heavier material as the structural part of the rim. This is the reason composite rims exist, because the aerodynamic portion of the rim can be made of a different and lighter material.

The CXP-33 is not 33mm deep. From the name, it seems like it should be, especially considering that the old CXP30 was 30mm deep. It's actually 23.5mm deep.

A 30mm rim is the deepest non-composite rim that I know of; anything deeper than that, and they get exceedingly heavy. Even the CXP30 is sort of a beast to haul around corners.
